(Embodiment 1)
With reference to FIG. 1, a telemeter system 100 according to Embodiment 1 of the present invention will be described. FIG. 1 is a block diagram showing the configuration of a telemeter system 100 according to the first embodiment.

As shown in FIG. 1, the telemeter system 100 includes a communication device 1, a meter 2, a server 3, and a center device 4. In the first embodiment, a telemeter system 100 includes a plurality of communication devices 1, a plurality of meters 2, a server 3, and a center device 4. The telemeter system 100 is a system that collects information indicating the measurement results of the meter 2. More specifically, the telemeter system 100 is a system in which the communication device 1 transmits information indicating the measurement results of the meter 2 to the center device 4, and causes the center device 4 to collect information indicating the measurement results. The server 3 and the center device 4 are, for example, a center system. The center device 4 executes information control on the communication device 1, for example.

The meter 2 is a measuring device related to resources or energy. The meter 2 measures, for example, gas, water, or electricity. The meter 2 is installed for each consumer such as a private residence, a company, and various facilities, for example. That is, the meter 2 is, for example, a measuring device that measures the amount of gas, water, or electricity used and outputs a measured value as a measurement result. The meter 2 is replaced, for example, at regular intervals. Further, when a malfunction occurs in the meter 2, the meter 2 is replaced. The meter 2 is an example of a "measuring device". Hereinafter, in this specification, a case where the meter 2 is a gas meter that measures the amount of gas used will be described as an example.

The meter 2 is installed, for example, in a gas pipe. Gas, which is the object of measurement by the meter 2, flows through the gas pipe. Gas is supplied to consumers from gas cylinders or gas holders through gas pipes. Note that the gas to be measured by the meter 2 may be LP gas (liquefied petroleum gas) or city gas. The meter 2 measures the amount of gas used by measuring the flow rate of gas flowing through the gas pipe. Note that the type of meter 2 is not particularly limited. The meter 2 is, for example, a 5-bit meter, an 8-bit meter, a U-bus meter, or a microcomputer meter. In the first embodiment, meter 2 is a 5-bit meter.

Although the meter 2 will be described as an example of a measuring device, as long as the measuring device is related to resources or energy, the measuring device may be, for example, an on/off sensor included in a gas cutoff device. A gas cutoff device is provided in the gas pipe. For example, when an earthquake is detected, the on-off sensor turns on and shuts off the gas pipe. That is, the flow of gas in the gas pipe is cut off. Note that when no earthquake occurs, the on-off sensor is in an off state. When the on-off sensor is in the off state, gas flow is allowed. Gas flow indicates that gas flows through the gas pipe. The communication device 1 transmits information indicating that the on-off sensor is turned on to the center device 4 as a measurement result.

The communication device 1 is installed for each meter 2 (measuring device). Further, the communication device 1 is installed, for example, on a wall around the meter 2 or on a gas cylinder. During the installation work of the meter 2, the worker operates the communication device 1 to set the communication device 1 so that the communication device 1 can transmit the measurement results of the meter 2 to the center device 4. Specifically, the worker operates the communication device 1, sets the operation mode of the communication device 1, and sets the communication device 1 so that the communication device 1 can transmit the measurement results of the meter 2 to the center device 4. do. In the first embodiment, the communication device 1 has multiple operation modes.

The operation mode of the communication device 1 includes an operation mode related to communication between the communication device 1 and the center device 4. In the first embodiment, the operation modes related to communication between the communication device 1 and the center device 4 are, for example, "field strength measurement", "opening call", "maintenance", "U terminal forced setting", and "AT command". The details will be described later. Therefore, during the installation work of the meter 2, the worker can cause the communication device 1 to start an operation mode related to communication between the communication device 1 and the center device 4. As a result, the communication device 1 is set so that the measurement results of the meter 2 can be transmitted to the center device 4. Further, the operation mode of the communication device 1 includes an operation mode determined for each type of meter 2. The operation modes determined for each type of meter 2 will be described later.

The communication device 1 is communicably connected to the meter 2 by wire or wirelessly. In Embodiment 1, the plurality of communication devices 1 are each wired connected to the plurality of meters 2 by electric wires PL. The electric wire PL includes a signal line and a ground line.

Each of the plurality of communication devices 1 and the center device 4 are connected to be able to communicate wirelessly. Specifically, each of the plurality of communication devices 1 and the center device 4 are, for example, a PHS (Personal Handy-phone System) network, a FOMA (Freedom of Mobile Multimedia Access) network, an LTE (Long Term Evolution) network, 4G (4th generation mobile communication system) network, and a wide area wireless network Ne such as a 5G (5th generation mobile communication system) network. Each of the plurality of communication devices 1 and the center device 4 perform wireless communication with each other via the wide area wireless network Ne.

The center device 4 collects information indicating the measurement results of each of the plurality of meters 2 via the communication device 1 . Specifically, the center device 4 collects the measurement values measured by each of the plurality of meters 2 via the communication device 1 . Then, the center device 4 stores the collected measurement values in the server 3, for example. The server 3 is, for example, a database server.

Next, the communication device 1 will be explained with reference to FIG. FIG. 2 is a block diagram showing the configuration of the communication device 1. As shown in FIG. As shown in FIG. 2, the communication device 1 includes a housing Ca, a substrate Cb, and a battery Ba.

The casing Ca accommodates the board Cb and the battery Ba. The housing Ca is, for example, a hollow member. The casing Ca is made of a material that does not block magnetism, such as resin. Further, the housing Ca is, for example, waterproofed.

The board Cb includes a control section 10, a trigger section 20, an attitude detection section 30, a communication section 40, a notification section 50, a first connection section 60, a second connection section 70, and a third connection section 80. and a power supply control section 90 are installed.

Power supply control section 90 is connected to battery Ba. The power supply control unit 90 converts the power supply voltage supplied from the battery Ba into an internal power supply voltage, and supplies internal power to the control unit 10, the trigger unit 20, the attitude detection unit 30, the communication unit 40, and the notification unit 50. Supply power voltage.

The control unit 10 includes a processor 11 such as a CPU (Central Processing Unit) and an MPU (Micro Processing Unit), and a storage unit 12. The processor 11 controls each element of the communication device 1 by executing a computer program stored in the storage unit 12.

The storage unit 12 includes, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), and/or a semiconductor memory such as a flash memory. The storage unit 12 stores various computer programs executed by the processor 11. The storage unit 12 also stores a table 121. In the table 121, information indicating the attitude of the communication device 1 and the operation mode are associated. Details of the table 121 will be described later. The storage unit 12 may further store, for example, a log of communication between the communication device 1 and the center device 4.

The trigger unit 20 generates a trigger signal (hereinafter sometimes referred to as trigger signal SG) in response to an external operation. The trigger section 20 includes a magnetic sensor 21 in the first embodiment. The magnetic sensor 21 is, for example, a Hall sensor. The external operation is, for example, an operation of bringing the magnet Mg close to the magnetic sensor 21 via the casing Ca to the extent that the magnetic sensor 21 can detect the magnetic field of the magnet Mg. That is, the trigger section 20 generates the trigger signal SG according to the magnetic field of the magnet Mg. In the first embodiment, the magnet Mg is a separate member from the communication device 1. Therefore, the trigger section 20 can be placed inside the housing Ca. As a result, it is not necessary to provide a physical key for generating a trigger signal on the outside of the casing, so the cost for waterproofing the casing Ca can be reduced. In turn, the manufacturing cost of the communication device 1 can be reduced. Note that the external operation is preferably a non-contact operation from the viewpoint of waterproofing, but may be a contact operation.

The attitude detection unit 30 detects the attitude of the communication device 1 (for example, the tilt of the communication device 1). In the first embodiment, the posture detection unit 30 includes, for example, an acceleration sensor 31 that detects acceleration. Therefore, the manufacturing cost of the attitude detection section 30 can be reduced. As a result, the manufacturing cost of the communication device 1 can be reduced. Note that the posture detection unit 30 may include a gyro sensor in addition to or instead of the acceleration sensor 31.

Acceleration sensor 31 detects acceleration according to the attitude of communication device 1 . Posture detection section 30 outputs the detection result of acceleration sensor 31 to control section 10 . The detection result of the acceleration sensor 31 is output from the attitude detection section 30 to the control section 10 via a serial bus such as I2C (Inter-Integrated Circuit). The control unit 10 determines the attitude of the communication device 1 based on the detection result of the acceleration sensor 31 output to the attitude detection unit 30. That is, the control unit 10 analyzes the detection result of the acceleration sensor 31 output to the attitude detection unit 30 and determines the attitude of the communication device 1. The acceleration sensor 31 is, for example, a three-axis acceleration sensor. Note that, for example, the acceleration sensor 31 may be a two-axis acceleration sensor.

The communication unit 40 is connected to the wide area wireless network Ne and performs wireless communication via the wide area wireless network Ne. The communication unit 40 is, for example, a wireless communication module that complies with the communication protocol of the wide area wireless network Ne.

The notification unit 50, for example, notifies the worker of information to be notified. Specifically, the notification unit 50 reports the type of operation mode of the communication device 1. In the first embodiment, the notification unit 50 includes, for example, one or more LEDs (Light Emitting Diodes). For example, the type of operation mode of the communication device 1 is notified to the operator by lighting an LED in a lighting pattern according to the type of operation mode of the communication device 1 . That is, the LED has multiple lighting patterns. For example, the color of the light emitted by the LED and/or the period at which the LED blinks differs for each lighting pattern. Therefore, the operator can confirm the type of operation mode of the communication device 1 through the notification unit 50. As a result, erroneous operations of the communication device 1 can be effectively suppressed. Note that, for example, when the communication device 1 is in a standby state, the LED of the notification unit 50 is in a non-lit state.

In the first embodiment, the notification section 50 includes two LEDs. One of the two LEDs (hereinafter sometimes referred to as a first LED) lights up in a lighting pattern according to the type of operation mode of the communication device 1, for example. The other LED of the two LEDs (hereinafter sometimes referred to as a second LED) lights up, for example, according to the result of the communication device 1 operating in an operation mode depending on the attitude of the communication device 1. Therefore, in addition to the type of operation mode of the communication device 1, the operator can check the result of the operation of the communication device 1 through the notification unit 50. As a result, erroneous operations of the communication device 1 can be more effectively suppressed.

Note that the notification section 50 may include a speaker, a buzzer, or a vibration element. For example, when the notification unit 50 includes a speaker, the speaker notifies the operator of the type of operation mode of the communication device 1 by outputting a sound indicating the type of operation mode. Further, for example, when the notification unit 50 includes a buzzer, the buzzer outputs a sound the number of times corresponding to the type of operation mode, thereby notifying the operator of the type of operation mode of the communication device 1. For example, when the notification unit 50 includes a vibration element, the vibration element vibrates the number of times corresponding to the type of operation mode, thereby notifying the operator of the type of operation mode of the communication device 1. Therefore, since the notification unit 50 includes a speaker, a buzzer, or a vibration element, there is no need to provide a window in the housing for checking whether the LED is turned on, so that the waterproofness of the housing Ca can be further improved.

Furthermore, the notification section 50 may include a liquid crystal panel. When the notification unit 50 includes a liquid crystal display panel, the liquid crystal display panel notifies the operator of the type of operation mode of the communication device 1 by displaying an image indicating the type of operation mode. Therefore, even if loud sounds (for example, noise) are generated around the worker who operates the communication device 1, the worker can confirm the type of operation mode of the communication device 1.

An electric wire PL connected to the meter 2 is connected to the first connection portion 60 . That is, the first connection section 60 is wired connected to the meter 2 via the electric wire PL. The control unit 10 acquires information indicating the measurement results of the meter 2 via the electric wire PL and the first connection unit 60. In the first embodiment, the types of meters 2 that can be connected to the first connection section 60 are, for example, a 5-bit meter, a U-bus meter, or a microcomputer meter. In the first embodiment, the type of meter 2 is a 5-bit meter. Therefore, the electric wire PL connected to the meter 2 is connected to the first connection part 60. The first connecting portion 60 is an example of a “connecting portion”.

An electric wire PL connected to a measuring device can be connected to the second connecting portion 70. The type of measuring device that can be connected to the second connection section 70 is, for example, an 8-bit meter. An electric wire PL connected to a measuring device can be connected to the third connecting portion 80. The type of measuring device that can be connected to the third connection section 80 is, for example, an on-off sensor.

When installing the meter 2, the worker sets the type of the meter 2 to be connected to the first connection part 60, the second connection part 70, or the third connection part 80 in the communication device 1. When setting the type of meter 2 to the communication device 1, for example, the operator sets the communication device 1 to one of the operation modes determined for each type of meter 2 among the plurality of operation modes that the communication device 1 has. Let it start. In the first embodiment, the operation modes defined for each type of meter 2 include, for example, "U-bus meter", "5-bit meter", "microcomputer meter", "8-bit meter", and "on-off sensor", Details will be described later. The operator causes the communication device 1 to start an operation mode determined for each type of meter 2, and determines the type of meter 2 to be connected to the first connection part 60, the second connection part 70, or the third connection part 80. Set to communication device 1. In the first embodiment, since the type of meter 2 is a 5-bit meter, the operator causes the communication device 1 to start the "5-bit meter" operation mode.

According to the first embodiment, the operation mode determined for each type of meter 2 is applicable to a plurality of types of meters 2 (specifically, a 5-bit meter, a U-bus meter, and a microcontroller) that can be connected to the first connection section 60. meter). That is, the first connection portion 60 is common to a plurality of operation modes. Therefore, any one of a plurality of types of meters 2 can be connected to the first connection part 60. As a result, the communication device 1 can be configured without mounting a connection section for each type of meter 2 on the board Cb. As a result, the configuration of the communication device 1 can be simplified.

Next, with continued reference to FIG. 2, a method of setting the communication device 1 will be described. In the first embodiment, in order to cause the communication device 1 to start a desired operation mode, the operator first positions the communication device 1 in a posture corresponding to the desired operation mode. Then, the worker performs an external operation on the communication device 1 while maintaining the posture of the communication device 1. That is, the worker brings the magnet Mg close to the magnetic sensor 21 while maintaining the posture of the communication device 1 .

In the first embodiment, when the magnetic sensor 21 detects the magnetic field of the magnet Mg, the trigger unit 20 generates the trigger signal SG1 for starting the operation mode as the trigger signal SG. Specifically, when the magnetic sensor 21 detects the magnetic field of the magnet Mg before the communication device 1 starts an operation mode according to the attitude of the communication device 1, the trigger unit 20 changes the operation mode as the trigger signal SG. A starting trigger signal SG1 is generated. The operation mode start trigger signal SG1 is an example of a "first trigger signal."

The control unit 10 starts an operation mode according to the attitude of the communication device 1 in response to the operation mode start trigger signal SG1. Therefore, it is possible to cause the communication device 1 to start a desired operation mode without pressing a physical key such as a dip switch that may be provided in the communication device. As a result, the operator can easily set the desired operation mode. Note that the communication device 1 may or may not be provided with a physical key.

When terminating the operation mode, the operator performs an external operation on the communication device 1. That is, the operator brings the magnet Mg close to the magnetic sensor 21 in order to end the operation mode. When the magnetic sensor 21 detects the magnetic field of the magnet Mg after the start of the operation mode, that is, while the communication device 1 is operating in the operation mode according to the attitude of the communication device 1, the trigger unit 20 detects the magnetic field as the trigger signal SG. A trigger signal SG2 for ending the operation mode is generated. The operation mode termination trigger signal SG2 is an example of a "second trigger signal."

The control unit 10 terminates the operation mode according to the attitude of the communication device 1 in response to the operation mode termination trigger signal SG2. Therefore, the external operation for starting the operating mode and the external operation for terminating the operating mode are the same. As a result, a dedicated trigger unit only for generating the trigger signal for ending the operation mode can be omitted, and the communication device 1 can be simplified.

Next, the acceleration sensor 31 will be explained with reference to FIG. FIG. 3 is a perspective view showing the board Cb on which the acceleration sensor 31 is mounted. FIG. 3 shows an X-axis, a Y-axis, and a Z-axis that are orthogonal to each other. The X-axis, Y-axis, and Z-axis are coordinate axes fixed to the acceleration sensor 31.

In the first embodiment, the acceleration sensor 31 is fixed to the substrate Cb. That is, the X-axis, Y-axis, and Z-axis of the acceleration sensor 31 are fixed to the communication device 1. Therefore, the X-axis tilt, Y-axis tilt, and Z-axis tilt of the acceleration sensor 31 indicate the X-axis tilt, Y-axis tilt, and Z-axis tilt of the communication device 1, respectively. For example, the Z axis is perpendicular to the substrate Cb. The size of one side of the acceleration sensor 31 is, for example, approximately 2 mm. The acceleration sensor 31 is, for example, a semiconductor type acceleration sensor such as a capacitance type or a piezoresistive type.

The acceleration sensor 31 detects, for example, acceleration in the X-axis direction, acceleration in the Y-axis direction, and acceleration in the Z-axis direction. Then, the acceleration sensor 31 outputs to the control unit 10 a first acceleration signal indicating acceleration in the X-axis direction, a second acceleration signal indicating acceleration in the Y-axis direction, and a third acceleration signal indicating acceleration in the Z-axis direction. . The control unit 10 determines the attitude of the communication device 1 based on the first acceleration signal, the second acceleration signal, and the third acceleration signal. Specifically, the control unit 10 determines the X-axis tilt, Y-axis tilt, and Z-axis tilt of the communication device 1 based on the first acceleration signal, the second acceleration signal, and the third acceleration signal. do. For example, when the substrate Cb is tilted around the X-axis, the control unit 10 determines the Y-axis tilt and the Z-axis tilt of the communication device 1.

For example, the acceleration sensor 31 can detect gravitational acceleration when the communication device 1 is in a stationary state. In this case, when the communication device 1 is in a stationary state, each axis (X-axis, Y-axis, and Z-axis) of the acceleration sensor 31 detects each component of gravitational acceleration. Specifically, when the communication device 1 is in a stationary state, the first acceleration signal of the acceleration sensor 31 indicates the X component of the gravitational acceleration, the second acceleration signal of the acceleration sensor 31 indicates the Y component of the gravitational acceleration, and the acceleration The third acceleration signal of the sensor 31 indicates the Z component of the gravitational acceleration. The control unit 10 analyzes the first acceleration signal, the second acceleration signal, and the third acceleration signal output by the acceleration sensor 31, and determines the attitude of the communication device 1.

Next, the table 121 stored in the storage unit 12 will be explained with reference to FIG. 4. FIG. 4 is a diagram showing the table 121. Hereinafter, the table 121 stored in the storage unit 12 according to the first embodiment may be referred to as a table 121a.

As shown in FIG. 4, in the first embodiment, the storage unit 12 stores a table 121a. In the table 121a, the operation mode of the communication device 1, information indicating the attitude of the communication device 1, and the lighting pattern by the notification unit 50 are associated. The information indicating the attitude of the communication device 1 includes information indicating the X-axis inclination of the communication device 1, information indicating the Y-axis inclination, and information indicating the Z-axis inclination. In the table 121a, the tilt is expressed as a tilt angle. Note that the information indicating the attitude of the communication device 1 associated with the operation mode of the communication device 1 is an example, and is not particularly limited. Further, the type of operation mode of the communication device 1 is also an example, and is not particularly limited.

The control unit 10 detects the communication device 1 based on the detection result of the attitude of the communication device 1 by the attitude detection unit 30 (specifically, based on the detection result of the acceleration by the acceleration sensor 31 according to the attitude of the communication device 1). Determine the posture of 1. Then, the control unit 10 refers to the table 121a and determines the operation mode and lighting pattern according to the attitude of the communication device 1.

Note that the attitude of the communication device 1 determined by the control unit 10 and the information indicating the attitude of the communication device 1 in the table 121a do not need to completely match. For example, if the difference between the information indicating the attitude of the communication device 1 in the table 121a and the information indicating the attitude of the communication device 1 determined by the control unit 10 is 5° or less, the information indicating the attitude of the communication device 1 determined by the control unit 10 is The information indicating the attitude may be determined to correspond to the information indicating the attitude of the communication device 1 in the table 121a. For example, when the inclination of the X-axis of the communication device 1 determined by the control unit 10 is greater than or equal to +85° and less than or equal to +95°, the control unit 10 determines that the inclination of the X-axis of the communication device 1 is +90°. It may be considered. The same applies to the Y-axis inclination and the Z-axis inclination.

For example, if the information indicating the attitude of the communication device 1 determined by the control unit 10 is that the inclination of the X axis is +86°, the inclination of the Y axis is +87°, and the inclination of the Z axis is 0°, the control unit 10 The unit 10 considers that the inclination of the X-axis of the communication device 1 is +90°, the inclination of the Y-axis is +90°, and the inclination of the Z-axis is 0°. In this case, the control unit 10 determines the operation mode of the communication device 1 to be "AT command".

Note that if the information indicating the attitude of the communication device 1 determined by the control unit 10 does not correspond to any of the information indicating the attitude of the communication device 1 in the table 121a, the control unit 10, for example, It is also possible to wait until the posture corresponds to one of the operating modes.

For example, for "electric field strength measurement" as the operation mode, the posture of the communication device 1 is such that the X-axis tilt is 0°, the Y-axis tilt is +90°, and the Z-axis tilt is +90°; It is associated with lighting pattern 1. "Field strength measurement" as an operation mode is a mode in which the communication device 1 measures the radio field strength of a signal transmitted from a base station at a predetermined period. In "electric field strength measurement" as the operation mode, for example, when the electric field strength as a measurement result is strong, the second LED lights up in green. Further, for example, when the electric field strength is medium, the second LED lights up in orange. Further, for example, when the radio field intensity is low, the second LED lights up in red. For example, if the radio field strength is low, the operator changes the mounting position of the communication device 1 and causes the communication device 1 to start the "field strength measurement" operation mode again.

For example, for "open call" as the operation mode, the posture of the communication device 1 is such that the X-axis tilt is 0 degrees, the Y-axis tilt is -90 degrees, and the Z-axis tilt is -90 degrees. and lighting pattern 2 are associated with each other. The "opening call" operation mode is a mode in which the worker notifies the center device 4 that the installation work of the meter 2 has been completed. That is, after the installation work of the meter 2 is completed, the worker causes the communication device 1 to start the "opening call" as the operation mode. In the "opening call", the communication device 1 receives information about the consumer to whom the meter 2 is attached from the center device 4, and sets the received information in the communication device 1.

For example, "maintenance" as the operation mode includes the attitude of the communication device 1 in which the X-axis tilt is +90°, the Y-axis tilt is 0°, and the Z-axis tilt is +90°, and the lighting pattern. 3 is associated. In "maintenance" as the operation mode, for example, when the control unit 10 of the communication device 1 is operating, the second LED lights up in red. Further, for example, when the communication unit 40 of the communication device 1 is communicating, the second LED lights up in orange. Furthermore, for example, when the communication device 1 is communicating with the meter 2, the second LED lights up in green.

For example, for "U terminal forced setting" as the operation mode, the communication device 1 has an X-axis inclination of -90°, a Y-axis inclination of 0°, and a Z-axis inclination of -90°. The posture and the lighting pattern 4 are associated. "U terminal forced setting" as an operation mode is used when a meter 2 of a type different from the U bus meter and connectable to the first connection part 60 is set for the communication device 1. This is a mode for connecting a bus meter setting device (not shown) to the communication device 1 and causing the setting device and the communication device 1 to communicate. The setting device is a device that can communicate with the communication device 1 and the center device 4. The setting device is, for example, a tablet terminal device, a notebook computer, or a smartphone. In "U terminal forced setting", the setting device sets setting information for the communication device 1, for example. The setting information indicates, for example, the identification number of the communication device 1, the current time, and/or the wireless channel.

For example, an "AT command" as an operation mode includes the attitude of the communication device 1 in which the X-axis tilt is +90°, the Y-axis tilt is +90°, and the Z-axis tilt is 0°, and Pattern 5 is associated. “AT command” as an operation mode is a mode in which an external device (for example, a notebook computer) directly communicates with the communication unit 40 without going through the control unit 10. In the "AT command", the external device controls the communication unit 40 using an AT command.

For example, "reset" as the operation mode requires an attitude of the communication device 1 in which the inclination of the X-axis is 0°, the inclination of the Y-axis is 0°, and the inclination of the Z-axis is 0°, and the lighting pattern. 6 is associated. “Reset” as an operation mode is a mode for resetting information set in the communication device 1.

That is, according to the reference attitude detection trigger signal SG3, the attitude detection unit 30 detects the attitude of the communication device 1x when the reference attitude detection trigger signal SG3 is generated. More specifically, the attitude detection unit 30 detects the attitude of the communication device 1x maintained for a predetermined period of time after the reference attitude detection trigger signal SG3 is generated. The predetermined time is, for example, 3 seconds. Then, the control unit 10 determines the reference attitude of the communication device 1x based on the detection result of the attitude detection unit 30.

Next, the worker positions the communication device 1x in a posture corresponding to the desired operation mode. For example, the operator rotates the communication device 1x about the Z axis orthogonal to the substrate Cb while placing the communication device 1x on the stand. Then, the worker performs an external operation on the rotated communication device 1x. That is, the worker brings the magnet Mg close to the magnetic sensor 21 while maintaining the posture of the communication device 1x that has been rotated and changed its posture. In the second embodiment, when the magnetic sensor 21 detects the magnetic field of the magnet Mg for the second time before the communication device 1x starts the operation mode according to the attitude of the communication device 1x, the trigger unit 20 detects the magnetic field for the second time. A trigger signal SG1 is generated.

Further, the type of operation mode of the communication device 1x is also an example, and is not particularly limited.

The control unit 10 determines the reference posture based on the detection result of the attitude of the communication device 1x by the attitude detection unit 30 (specifically, based on the detection result of the acceleration by the acceleration sensor 31 according to the attitude of the communication device 1x). The attitude of the communication device 1x relative to the position is determined. Then, the control unit 10 refers to the table 121b and determines the operation mode and lighting pattern according to the attitude of the communication device 1x with respect to the reference attitude.

Note that the attitude of the communication device 1x determined by the control unit 10 and the information indicating the attitude of the communication device 1x in the table 121b may not completely match. For example, if the difference between the information indicating the attitude of the communication device 1x in the table 121b and the information indicating the attitude of the communication device 1x is 5 degrees or less, the information indicating the attitude of the communication device 1x determined by the control unit 10 is It may be determined that the information corresponds to the information indicating the attitude of the communication device 1 in the table 121b.

Specifically, for example, an LED included in the notification unit 50 lights up to notify the operator of the determination of the reference posture of the communication device 1x.

In step S40, the operator positions the communication device 1x in a posture corresponding to the desired operation mode. For example, the operator rotates the communication device 1x about the Z-axis of the communication device 1x while placing the communication device 1x on a stand until the communication device 1 assumes a posture associated with a desired operation mode.

In step S42, the worker performs an external operation on the rotated communication device 1x.

Next, with reference to FIG. 8, a communication device 1y according to the third embodiment will be described. The third embodiment differs from the first embodiment in that the attitude detection unit 30y of the communication device 1y includes a geomagnetic sensor 32. Hereinafter, regarding Embodiment 3, matters that are different from Embodiment 1 will be described, and descriptions of parts that overlap with Embodiment 3 will be omitted.

FIG. 8 is a block diagram showing a communication device 1y according to the third embodiment. As shown in FIG. 8, the communication device 1y includes a housing Ca, a board Cby, and a battery Ba.

The geomagnetic sensor 32 detects, for example, geomagnetism. The attitude detection section 30 outputs the detection result of the geomagnetic sensor 32 to the control section 10. The control unit 10 determines the attitude of the communication device 1y based on the detection result of the geomagnetic sensor 32 output to the attitude detection unit 30. The geomagnetic sensor 32 is, for example, a Hall sensor, an MR (Magneto Resistance) sensor, or an MI (Magneto Impedance) sensor.

Next, the geomagnetic sensor 32 will be explained with reference to FIG. FIG. 9 is a perspective view showing the board Cby on which the geomagnetic sensor 32 is mounted. Moreover, FIG. 9 shows a board Cby mounted on a communication device 1y mounted on a stand having a substantially horizontal surface. In the third embodiment, the geomagnetic sensor 32 is fixed to the substrate Cby. The size of one side of the geomagnetic sensor 32 is, for example, approximately 2 mm.

Specifically, the geomagnetic sensor 32 detects, for example, the rotation angle with respect to the reference direction Ad when the communication device 1y (board Cby) rotates about the reference line AX. Then, the geomagnetic sensor 32 outputs a rotation angle signal indicating the detected rotation angle to the control unit 10. The control unit 10 determines the attitude of the communication device 1y based on the rotation angle signal. The reference line AX is, for example, parallel to the substrate Cby. When the communication device 1y (board Cby) is placed on a stand having a horizontal surface, the reference line AX is parallel to the vertical direction.

A trigger signal SG4 for setting the reference direction is generated.

In response to the reference direction setting trigger signal SG4, the attitude detection unit 30y detects the reference direction Ad of the communication device 1y when the reference direction setting trigger signal SG4 was generated. Specifically, the attitude detection unit 30y detects the reference direction Ad when the attitude of the communication device 1x is maintained for a predetermined period of time after the reference direction setting trigger signal SG4 is generated. The predetermined time is, for example, 3 seconds. Then, the control unit 10 sets a reference direction Ad of the communication device 1y based on the detection result of the attitude detection unit 30.

Next, the worker places the communication device 1y in a posture corresponding to the desired operation mode. For example, the communication device 1y is rotated on a table about the reference line AX. Then, the worker performs an external operation on the rotated communication device 1y. That is, the worker brings the magnet Mg close to the magnetic sensor 21 while maintaining the posture of the rotated communication device 1y. In the third embodiment, when the magnetic sensor 21 detects the magnetic field of the magnet Mg for the second time before the communication device 1y starts an operation mode according to the attitude of the communication device 1y, the trigger unit 20 detects the magnetic field for starting the operation mode. A trigger signal SG1 is generated.

Specifically, the control unit 10 starts an operation mode according to the rotation angle of the communication device 1y with respect to the reference direction Ad in response to the operation mode start trigger signal SG1.

Next, with reference to FIG. 10, the table 121 stored in the storage unit 12 according to the fourth embodiment will be described.

The information indicating the attitude of the communication device 1y includes information indicating the rotation angle of the communication device 1y with respect to the reference direction Ad. Note that the information indicating the attitude of the communication device 1y associated with the operation mode of the communication device 1y is an example, and is not particularly limited. Further, the type of operation mode of the communication device 1y is also an example, and is not particularly limited.

The control unit 10 detects the attitude of the communication device 1y based on the detection result of the attitude of the communication device 1y by the attitude detection unit 30 (specifically, based on the detection result of the geomagnetic sensor 32 according to the attitude of the communication device 1y). Determine your posture. Then, the control unit 10 refers to the table 121c and determines the operation mode and lighting pattern according to the attitude of the communication device 1y.

Note that the attitude of the communication device 1y determined by the control unit 10 and the information indicating the attitude of the communication device 1y in the table 121c do not need to completely match. For example, if the information indicating the attitude of the communication device 1y determined by the control unit 10 is less than ±5° with respect to the information indicating the attitude of the communication device 1y in the table 121c, then the information indicating the attitude of the communication device 1y determined by the control unit 10 is The information indicating the attitude may be determined to correspond to the information indicating the attitude of the communication device 1y in the table 121c. For example, when the rotation angle of the communication device 1y determined by the control unit 10 is 35°, the control unit 10 determines the operation mode to be “field strength measurement”.

Next, a method for setting the communication device 1y according to the third embodiment will be described with reference to FIG. 11.
